Dreaming that you are (or someone is) alert, awake, or conscious could represent awareness, paying attention, mental focus, or a thought process (or perhaps your belief that you or someone else needs more of such).
Receiving an alert or notification (such as on your phone) can represent communication, news, a change, or something that needs your attention (or a desire for or fear of such).
